I think
you should tell her
that you understand how she feels and
will respect those feelings and not bother her anymore, and stand by these words. If she truly loves you and there is just a glimmer of her wanting to work thru this, then your absence will make it happen. She needs to "miss you" so that she can think about everything. Your absence may make her realize that she can get over this, if not, then you just have to accept that it's over, learn by it and move on.
